Same, of which the following is a specification.

Thls invention relates to receptacles,

tubes, conduits, or the like, and to the proc- I vess of making the same.

appended claims.

The object of the invention is to provide a tube, conduit, receptacle, or the like, of non metallic substance, which is strong, and durable, economical of manufacture and efficient forthe purposes for which such articles are applied.

A further object of the invention is to provide a novel, eflicient and economical process of manufacturing tubes, receptacles,

or the like.

Further objects of the invention will ap' pear more fully hereinafter.

. The invention consists substantially in the combination, location and relative arrangement of parts, together with the process employed in connection therewith, all as will be more fully hereinafter set forth as shown by the accompanying drawing and finally pointed out in the eferring to the drawing Figure 1 is a view of a portion of a mandrel on which has been applied the first layer of a tube.

Fig. 2 is a similar view, showing the second layer applied thereon. Fig. 3 is a similar. view showing the reinforcing elements applied thereon, the

broken end of the same being shownwith an outer surface layer, the whole constituting athree-ply tube.

Fig. 4 as a sectional view of the mandrel with the layers applied thereon.

Fig. 5 is a sectional view taken on the line 5-5 Fig. 4 and looking in the direction of the arrows. I

a Fig. 6 is a diagrammatic view of .a modified construction.

- Fig. 7 is a similar view of a further" modified construction.

The same part is designated by the same reference numeral wherever it throughout the several views.

OCCllI'S It is among the special purposes of present invention to provide a construc tion of tube, conduit, or the like, which maybe used for any purpose for which tubes, conduits, or the like, are used, or which may be cut up into desired lengths. and pro vided with caps, or the like to form in the usual well known manner, receptacles, cans,

carriers, or similar articles.

It is a further special purpose of my invention to provide articles of this nature of nonmetallic substance and to reinforce the same so that the strength of a metallic article is'secured at a great decrease in the cost of the materials employed, due to their non-metallic composition, thus enabling a cheap, water-proof, strong, durable, non- ,metallic article to take the place of the present expensive metallic article.

While I will now describe my invention j as applied to a three-ply conduit or tube, or the like, as illustrative of my invention, I wish it to be understood that I am not to be limited in this respect, as one or any number of plys may be employed. in accordance with the use to which the finished product is to beput. As is customary in the manufacture of tubes of this nature, the tube of my invention is wound upon a mandrel indicated at 1 at anydesired pitch. The inner surface or what'I will term the first-.

I ply-'2 is wound upon the mandrel in this manner with the edges of the strip of the 4 lfi-rst-ply abutting'against .each other, as shown.

This stripof first-ply may be of any de- I, sired material, preferably of-a fibrous material, and it may or may not be waterproofed, impregnated with wax, etc., as de-. sired. Likewise the width. of the strip, of

the first-ply may be of any desiredsize, de-

. pending entirely upon the requirements and the will of the manufacturer. After the first-ply has been wound on the 'mandrel,

the second-ply consisting of a strip, preferably, though not necessarily, of the same width as the first-ply strip, and made of. wood pulp or other similarly soft, pliable;

material, is wound around the first-ply at: preferably, though notnecessarily, at the same pitch as the .first-ply or innerlayer with the abutting edges of the softwood pulp strip positioned at a point intermediate the abutting edges of the inner surface or first-ply strlp, as clearly shown at three in Fig. 2 I One or more, and preferably a great number .of reinforcing strips 4 are then wound under tension around the second-ply. or wood pulp strip. Although I am not to be limited to the specific form shown, I find it preferable where a threeply inch strip of first and second ply is employed to use a number of reinforcing elements 4 positioned at approximately an eighth of an inch apart.

such as wire, strips of tin, or the like. I

find it preferable toemploy.round wire, reither copper, iron or steel, for this purpose. The wiremay be wound on the second-ply or wood pulp strip under any suitable. or desired tension, preferably of sufiicienttension to cause the same to sink into the wood pulp, at least to point flush with the surface thereof, as shown best in Figs ting edges of the plies. If desired, however,

the wires may be wound on the second-ply or wood pulp strip in a direction reverse to i the pitch of the wood pulp strip and firstply, as shown in Fig. 6. Likewise, ifdesired, the reinforcing wires 4 may be run 35.,in both directions to. effectively form a reinforcing mesh throughout the length of the tube without the disadvantages encountered in the use of a wire mesh in the 'first instancesuch as the cost of construction of the same and the necessity for treating the.

same to retain it in itsmeshed position. If

desired, and as shown, an outer surface or the third-ply 5 may then be wound around the reinforced wood pulp or second-ply with the abutting edges thereof preferably in alinement .with the abutting edges of the first-ply 2 and preferably of the same width of.strip and of the same pitch on the mandrel. The outer surface or third-ply 5, if desired, may be waterproofed in any suitable manner in accordance with the PHI? pose for which the completed tube is 'constructed. It is the general practice in the construction of articles of'this nature to make the same of an endless length to be cut oil 1n the desired sizes in accordance with the purposes for which the articles are to be employed. Receptacles, cans, or the like, are constructed in a; similar manner, cut ofi into the-desired sizes and provided with caps of any desired construction, which may be secured tothe top and bottom of the tube in the usual or any well known manner.

Having now set forth theobjects and na- The reinforcing n elements 4 may be of any desired material,
